SCRUBIBIN'G-MACHINE.

SPECIFICATION forming part of Letters latent No. 72 dated y 1903-Application filed February 9, 1903. serial No. 142,570. (No model.)

useful improvements in scrubbing-machines;

and more especially to that type in which a scrubbing-brush is mountedand carried witha water-carrier. a

Figure 1 is a side elevation of my improved scrubbing-machine. Fig. 2isa Vertical section thereof. taken on the line 3 3 of Fig. 1. I

In the construction illustrated in the drawings'I mount thewater-receptacle l-uponl wheels 2 and 2, while the axle 3 is madeintegral with the sides of tank. Secured to the inner face of wheel 2 isa large pinion 4, which is mounted on said wheel and held rigid thereonby-theuse of screw-pins 5, arranged in spokes of wheel. Themaster-pinion 4 meshes with a smaller'pinion 6, rigid-lymoun ted onshaft 7 of scrubbing-brush 8. The shaft of the scrubber is journaled ateach end in a downward-projectingportion9 of the tank. T0 evenlydistribute the water upon the surface of the bristles as it flows fromthe fanshaped nozzle 10, I suspend a wire mesh 11 from the bottom of thetank and in close proximity to the scrubbing-Wheel. This will dilfusethe water and give a better distribu-- tion upon the bristles.

Fig. 3 is a partial cross-section}.

I employ the ordinary ground-seated valve 12, pivoted at 13 on theupright rod 14. This Valve is normally kept closed by the tensionspring15 hearing against the bracket 16. 0

The spring in turn exerts a downward pressure upon washer 17, that isrigid on rod 14, thus seating the valve, and when the same is open itwill appear as shown in dotted lines of the drawings. moving theordinary screw-cap 18.

I do not wish to limit myself to the exact detailsof construction andoperation herein set forth, as I may make various changes in thesamejwithout-departing from the'spirit of myinvention.

. Having thus fully described myinvention, what Ifclaim as novel, anddesire to secure by Letters Patent, is-

'In a scrubbing-machine, a tank, a scrubhing-brush rotatable underthetank, a truck on which the tank is mounted; means for'driving the brushfrom the truck-wheels, aspout dischargin'g'from-the tankon the brush,

means for controllingthe flow of water-t0 the spout and a wire meshinterposed between the spout and brush. I r I In testimony whereof Iaffix my signature, in the presence of two witnesses,"this 6th day ofFebruary, 1903.
